Outputs to Inputs:
Depending on distance coax cable is probally the best way to go.
You need a dvd player with a coaxial output. Cable out of DVD player to a coax splitter. Run a cable to each TV
Without coax you'll need a splitter/amp to take signals from DVD player and send them to the TV's.
The logistics all depends on what your DVD outputs are, and what inputs your TV's have.
